Questions

Is there a KiCad symbol and footprint for the SC91F73M28U?

Yes. The symbol is EasyEDA_Cloud:SC91F73M28U and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SC91F73M28U?

SOP-28-300mil, with 28 pins. Its footprint is drawn on this page.

Where is the SC91F73M28U datasheet?

SOC publishes it: the Datasheet link on this page opens it.

Where can I order the SC91F73M28U?

JLCPCB lists it as part C221371, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SC91F73M28U?

Parts like it in the library: the PIC16F57-I/SO by Microchip Technology, the PIC16F876A-I/SO by Microchip Technology, the STC15W408AS-35I-SOP28 by STC Micro and the PIC16F1518-I/SO by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
